16GB DDR3L ECC RDIMM for Supermicro SuperServer

This 16GB DDR3L 1600 registered DIMM targets administrators upgrading Supermicro SuperServer 1027 and 2027 series platforms. The module delivers ECC protection and registered buffering required by those workstation and server boards. It will not function in standard desktop computers or alongside unbuffered memory.

Thermals noise and power draw

Operating at 1.35V, the DDR3L module reduces power consumption compared to standard 1.5V DDR3 while maintaining CL11 latency at 1600MHz. No heat spreader is fitted, so airflow across the DIMM slots handles cooling in typical server chassis. The registered design adds minimal electrical load per channel.

What the bundle changes

The single 240-pin 2Rx4 module installs directly into compatible SuperServer slots to expand capacity by 16GB per DIMM. JEDEC and RoHS compliance ensures the upgrade meets industry specifications without requiring configuration changes. Buyers needing larger capacities must populate additional slots with matching registered ECC modules.

Questions about this item

How do I install this 240-pin DDR3L RDIMM in a Supermicro SuperServer 1027 series, and what step do people often miss?

Power down the server, open the chassis, align the notch on the 240-pin module with the slot key, press firmly until both ejector clips lock, then enable ECC in the BIOS — the step most often missed.

What maintenance or replacement will this 16GB ECC Registered module need over its service life?

No routine maintenance is required; the module has no heat spreader or moving parts, so replacement is only needed if a memory test reports uncorrectable errors or if capacity must be increased beyond 16GB.

What limit appears first when this CL11 1.35V RDIMM runs under sustained server workloads?

The registered buffer adds one clock cycle of latency, so memory-controller throughput reaches its ceiling before the DRAM cells hit thermal or voltage limits.
